Title: Improved pole top fittings or crossarms for poles and masts carrying overhead lines
IPC: H02G7/20
Filed: 1943-04-12
Abstract: 566,036. Securing. cross-arms &c. for overhead lines to poles. KIDD, A. W. April 12, 1943, No. 5855. [Class 20 (i)] Top fittings or cross-arms on poles, for carrying overhead lines, are carried by a single channel member l which is bolted to the pole with the web outwards so that the edges of the flanges are in gripping engagement with the pole. A cross-arm a of tubular section is flattened at the ends to provide seatings for insulators d which are secured to the cross-arm by nuts and bolts e passing through the insulators and through distance tubes within the flattened ends of the cross-arm. The crossarms are sealed at the ends by welded &c. plates f to render the cross-arms weathertight. The cross-arms are carried by brackets p welded or otherwise fixed to the sides of the channel member l, the brackets having semicircular seats on to which the cross-arms are welded. The channel member may be extended upwardly and provided with a top plate r to form a seating for a third insulator s. For six overhead lines, three cross-arms are employed, each with its own channel bracket mounting. Where H-type poles are concerned, the crossarms each have two spaced channel brackets to engage the poles.

Title: Telecommunications installation which includes a gas-filled transmission line
IPC: G01M3/18
Filed: 1964-02-14
Abstract: 1,044,404. Selective signalling. TELEFUNKEN PATENTVERWERTUNGSGESELLSCHAFT. Feb. 14, 1964 [April 26, 1963; [Oct. 11, 1963], No. 6264/64. Heading G4H. The location and type of fault arising in a telecommunications installation incorporating a gas-filled cable is detected by the absence of one or more signals arriving at a central monitoring station from one or more supervisory stations each operating at different audiofrequencies and each connected via a portion of the cable to the central monitoring station. In the embodiment shown, each of the supervisory stations A-N supplies its associated section of the cable 1 with gas to make up for leakage and also provides two currents of different frequency which are amplified at LV in the central monitoring station Z before being selectively rectified according to frequency at U1-U26 to control warning apparatus in the form of lights L1-L26 and a common buzzer W. In one station A, one of the frequencies is supplied by a generator TG1 and the other is supplied by a generator TG2 through high resistance line couplings LK1 and LK2 and if the rate of gas supply from, e.g. the supervisory station A to its associated section of the cable 1, exceeds a predetermined level or the gas pressure in the cable falls too low, TG2 is automatically disconnected by a relay contact or electronic switch s. Also, if the gas supply in a cylinder in the supervisory station A should fall below a specified minimum TG1 is automatically disconnected by a relay d. The absence of the current from TG1 or TG2 causes corresponding alarm relays R1 or R2 to switch on the warning light L1 or L2 and the common buzzer W. The other supervisory stations operate in a similar manner and the supervisory stations nearer the central monitoring station operate at higher frequencies than those further away so that all the currents arriving at the amplifier LV undergo the same amount of attenuation.

Abstract: 1,134,992. Feeding webs. JAGENBERGWERKE A.G. 9 Feb., 1967 [24 March, 1966], No. 6265/67. Heading B6B. Web de-curling apparatus comprises a rod 4 freely rotatably supported against at least two support rollers 5 and 6 or a plurality of rollers axially spaced (Fig. 2). The rollers 5 and 6 are mounted between parallel plates 9, vertically -movably in rails 10 by screw jacks 17. A third support roller 12 is supported in rocking levers 13, the pivots 14 of which are fastened, to the plate 9. A fluid cylinder 16 urges the roller 12 against the rod 4. Rollers 5, 6 and 12 may be covered with a resilient material. The vertical movement of the rod 4 and support rollers relative to two guide rollers 2 and 3, and therefore the degree of de-curling, is dependent of the diameter of a supply roll (19, Figs. 3 and 4). The braking force applied to the supply roll spindle is proportional to the supply roll diameter, and this force is used in a known way to control the screw-jacks 17. Alternatively a feeler sensing the supply-roll diameter or a speed indicator such as a tachometer generator driven by the shaft of the supply-roll may be used. Rods 4 of various diameters may be used or the rod may be made of an elastic hollow body adapted to be inflated by introducing a pressure medium.

Title: Seismic record processing method and apparatus therefor
Inventor: GRAUL JOHN MICHAEL
IPC: G01V1/28
Filed: 1970-02-10
Abstract: 1294366 Seismic signal processing CHEVRON RESEARCH CO 10 Feb 1970 [10 Feb 1969] 6388/70 Heading H4D A composite seismic section, easier to interpret than one comprising only simulated traces obtained by a double "sonogramming" process on original traces, is produced by sonogramming original traces a group at a time to give sonogram traces, picking sonogram trace characteristics representing selected seismic data, sonogramming the picked characteristics to give a plurality of simulated seismic traces associated respectively with the original traces, then combining each original trace with its associated simulated trace to give respective combined traces constituting the composite seismic section. In the Fig. 1 embodiment an original seismic section comprising several statically and dynamically corrected multi-trace records recorded side-by-side on drum 11 is reproduced by an array of heads 15. With the array offset at a first angle the head outputs are summed at 19 and picked events selected at 21 are recorded by head 34 on drum 31 as a first "directional" sonogram trace. Further sonogram traces are recorded for different offset angles of head array 15, as side-by-side traces on drum 31 to complete the first sonogramming process. For the second sonogramming process, the sonogram traces are reproduced by an array of heads 37 at a first offset angle and certain ones selected at 20 are composited at 52 to give a first simulated seismic trace which is combined at 58 with a first of the original traces (reproduced by head 24) to give a first combined trace for recording by head 65 on drum 61. Further combined traces are then recorded for different offset angles of head array 37 to give a composite seismic section on drum 61. Since the sonogram traces on drum 31 are individually associated with particular values of dip of subsurface formations, coherent noise manifesting itself as false steep dip events can be eliminated from the composite section by dip selector 20 which includes (Fig. 5, not shown) switches and variable gain amplifiers for disconnecting, or reversing the polarity of, selected outputs of head array 37. Mixer 58 (Fig. 6, not shown) includes a patch-board for selectively applying non-linear amplifiers, phase-inverters or time-varying attenuators to the original trace signal from head 24 and simulated trace signal from summing amplifier 52, whereby these two signals can be selectively combined in timevarying proportions. The data processing may be done by digital computer instead of by the Fig. 1 analogue system.

Title: Improvements in instruments for measuring electric resistances
IPC: G01R27/14
Filed: 1929-02-28
Abstract: 319,578. Bozek, F. Feb. 28, 1929. Resistances, measuring. - Two incandescent lamps 6, 10, Fig. 1, such as torch lamps, are arranged in parallel circuits, of which one contains the resistance w to be measured and the other a known variable resistance 5. The two parallel circuits are included in a main circuit containing a rheostat 2 and a known variable resistance 3 and supplied from terminals 1, 11 of a high-tension battery. The resistances 3, 5 are of equal values and are so arranged that one is decreased and the other increased by the same amount. For preliminary setting the resistance 5 is set to zero and the resistance 3 to its maximum value. The rheostat 2 is adjusted until the lamp 6 glows with moderate luminosity. On shortcircuiting the terminals 8, 9 both lamps glow faintly. The resistance w to be measured, for example two earths, is then connected to the terminals 8, 9 and the resistances 3, 5 adjusted until the lamps 6, 10 glow with equal luminosity. The resistance w is then equal to the resistance 5. The rheostat 2 and high-tension battery may be replaced by an adjustable bell-transformer, alternating current being employed. In a modification, Fig. 4. in which a low-voltage source of current such as an accumulator or pocket-lamp battery is employed, a fixed resistance 17 is arranged in series with the lamp 26, and a known variable resistance 19 is in series with the lamp 27 and the resistance to be measured. Across the resistance to be measured is a shunt circuit containing a resistance 18 and terminals 24, 25 which may be short-circuited. The resistances 17, 18 are equal and each is of about 25 ohms in value. With the circuit containing the resistance open, the resistance to be measured is equal to the difference between the resistances 17, 19. For measuring resistances over 25 ohms, the terminals 24, 25 are short-circuited, the resistances 19 being provided with a second scale for direct reading under these conditions. The resistance 19 may be provided with a spring 20 and stop 22 for normally keeping a small resistance in circuit to prevent blowing out the lamp 27.

Abstract: 794,384. Impedance testing; fault testing. ERIE RESISTOR CORPORATION. March 2, 1956 [March 7, 1955], No. 6591/56. Class 37. Apparatus for testing a multiple terminal electrical impedance network by comparison with a similar standard or perfect network comprises plural sources of testing signal having substantially zero cross-correlation therebetween, each of which sources is connected to a terminal of the standard network and a corresponding terminal of the standard network to produce currents therein which are independent of the presence of the signal sources connected to other terminals; the difference between the currents flowing from each signal source to the test and standard network terminals operating a display device for indicating excess of such difference over a predetermined threshold, representing a predetermined difference input between test and standard impedance networks, whereby any departure of the test network from standard is indicated for each terminal thereof. A plug-in impedance network (Figs. 1 and 2, not shown) having 10 circularly disposed terminals a to j interconnected by resistances, capacitances, and inductances is plugged into test socket 6 (Fig. 3), while a similar standard network is plugged into test socket 8. Corresponding pairs of sockets a to j are respectively connected to the antiphased opposite ends of the secondaries 10 of transformers energized from individual oscillators, each operating at a distinct frequency fa to fj. The centre taps of the secondaries are respectively earthed over load resistances 13 to develop voltages proportionate to the difference between the currents flowing to the corresponding test and standard terminals, which are amplified and applied to operate signal lamps 15 at a threshold value representing the maximum tolerable deviation of a test network from standard for each particular terminal. The energizing frequencies may be derived from a wideband noise generator (Fig. 4, not shown), by a plurality of filters selecting non-overlapping frequency bands which are amplified for application to the respective transformers. The networks may contain non-linear elements such as germanium diodes if, in testing, the forward currents and the reverse currents in corresponding elements are combined in the detection circuits for alternate half-cycles of energization voltage.
